Olympic and world giant slalom champion Ted Ligety says he tore the ACL in his right knee during a training crash Wednesday in Oberjoch, Germany.
The 31-year-old from Utah used Facebook to post a video of his wipeout. He wrote: "We all know ski racing is a dangerous sport but I always thought I could avoid a season ender."
The U.S. Ski Team said in a release only that Ligety suffered a knee injury and will head home to be evaluated.
It's been a rocky season for Ligety, who is sixth in the GS standings -- a discipline he usually dominates. His only podium finish in the GS this season was a win in Austria three months ago. He took second in the super-G at Beaver Creek, Colorado, in December.
